I'm a new leather worker who has waded off into the craft more deeply and more suddenly than I had originally intended. After wet molding a Buck folding knife scabbard, my true first project was a basket weave 2" layered Ranger Duty belt to wear late in my career. I was profoundly shocked at how it turned out for my first build. I hand stitched that belt and while I truly love to saddle stitch, I can tell arthritis will become an issue at my age. I next bought a Cowboy 797 and made some belts on it followed by a Weaver Cub. While I've practiced a little with the Cub, I find it a little daunting still and have procrastinated using it on a serious project. But I did find on my first real attempt, when the thread tension fubared, I removed the thread and hand stitched as the stitch holes were perfect. On one more project, I used the Cub without thread just to punch a clean stitch line. This thread is giving me the confidence to see what I can do with it. I know now that if I stay in this craft, and likely will, I will one day step up to Class IV because historically, that's how I progress at things. But it seems other than having a reverse stitch, the Cub should do much of the same tasks as the Class IV at least for the heavy hobby user. I am still having difficulty turning my material 180 degrees to try to back stitch. Even with the needle down and lifting the presser foot, it sometimes seems the thread wants to bind and twist around the needle. I'm not sure back stitching is totally possible and certainly not sure I'm going about it correctly. If I can learn to make that happen, I think this Cub might do about all I need to do with thicker leather.
